Switching from HTTP to HTTP/2 producing exception

[redivo]

Trying to switch an older M1 project to HTTP2, hosted under Apache 2.4.25

As soon as I enable Apache HTTP/2 (enable modules mpm_event, https and php7.2_fpm), the server serves all websites via H2 without problems, except the one with Magento 1.9.4.1. Without H2 it works fine with the same PHP as a module. Both the backend and the frontend generate the following error messages. Does anyone have an idea how this comes about? I've searched the whole web but haven't found anyone with a similar problem.

Based on the error messages you provided, it appears that the Magento application is encountering issues with the HTTP/2 protocol. This is a known issue with Magento 1.9.4.1 and may require additional configuration changes to work properly with HTTP/2.

Here are a few things you can try to resolve the issue:

1. Check Magento version compatibility with HTTP/2: Magento 1.9.4.1 was released in March 2019, and it is possible that the code may not be fully compatible with HTTP/2. It is recommended that you check with Magento support or consult the Magento documentation to ensure that your version of Magento is compatible with HTTP/2.

2. Update Magento: If the Magento version is not compatible with HTTP/2, it may be necessary to upgrade to a newer version of Magento that supports HTTP/2.

3. Review Apache configuration: Check the Apache configuration file to ensure that the necessary settings for HTTP/2 are properly configured. For example, the SSLProtocol setting should be set to "TLSv1.2 h2 http/1.1" to enable HTTP/2.

4. Disable HTTP/2 for Magento site: If the above steps do not resolve the issue, you can try disabling HTTP/2 for the Magento site by adding the following line to the VirtualHost configuration file for the Magento site: "Protocols h2c http/1.1".

5. Check PHP module compatibility: Check that the PHP module you are using is compatible with HTTP/2. Some PHP modules may not work properly with the HTTP/2 protocol.

If none of the above steps resolve the issue, it may be necessary to consult a Magento developer or specialist to help diagnose and resolve the issue.

Switching to HTTP/2 with Magento 1.9.4.1 can be tricky, especially when compatibility issues arise. You might want to try tweaking your server settings or disabling certain modules to pinpoint the issue.

On a related note, if you’re troubleshooting server configurations and considering a break from it all, looking into a US tourist visa from UAE might be a great way to plan a stress-free trip once everything is sorted!

Switching server protocols can definitely introduce unexpected issues, especially with older Magento builds. It’s often worth reviewing your SSL configuration and checking if your hosting provider fully supports ALPN for HTTP/2.

And if you ever need a breather from debugging server settings, planning your next holiday can be a refreshing reset — you can even check  USA tourist visa from UAE options to start your next getaway once your site is running smoothly!
